Energy (Q) and power (P) are related by Q = Pt. This means the longer (t) you turn on a heater, the more heat (Q) it will produce. And the higher the power (P) is, the more heat (Q) it will produce.
Two identical, closed boxes each have a round heater at the center, with the power output as labeled. Instructions: 1) Run the model and turn the graph on to monitor the temperatures; 2) Use the buttons at the upper-right corner of the graph window to rescale the curves if necessary; 3) Calculate the ratio of the temperatures measured by the two thermometers in the two boxes and compare it with the ratio of the heating powers.
Power of heater 1
| 0 W/m3 | 1000 W/m3 |
Power of heater 2
| 0 W/m3 | 1000 W/m3 |
